03.Clear the Four Frozen Cave Stages

The original walkthrough shows four consecutive obstacle sections. Follow the images below to recognize each one.

Block Party

Cross the floating blocks quickly. The supplied walkthrough says you have about 4 seconds on each block.

Falling Rock

Watch the ceiling and pass between falling rocks. Do not stop under a drop zone.

Ghost Parkour

Keep running across the collapsing bridge before the platforms fall away.

Snowball

Dodge the rolling snowballs and reach the exit to enter the offering area.

04.Bring All Four Required Fish

You must provide one of each fish at the altar. The rarity and odds below come from the supplied fish-card screenshots — not an official published drop-rate table.

Reach the final chamber beyond Snowball.
Press E at each pedestal and place the matching fish.
Check the price at the central rod station. The player walkthrough lists 15T coins.
Purchase the Frostbite Rod when the requirements are met.
